No one yet knows just when men began to make fire themselves, but scientists believe that it happened very early in history. They say that it must have come about as a result of the observation of sparks. Hot sparks blown by the wind spread forest fires, and early toolmakers must have noticed that the rocks they chipped at often threw off similar sparks. It's likely that these first artisans obviously began to select those rocks that would make sparks every time they were struck. A very common mineral, iron pyrites, will give a shower of sparks when hit with another stone. Flint, the basis forany early tools, does this even better. This method of producing sparks by striking stones together is known as percussion, and all that is needed to start a fire is to direct the sparks to a pile of tinder made of dry leaves and tiny scraps of wood.

Many methods and devices have been invented to produce fire by rubbing wood together. Some are quite simple. The foresaw consisted of a serrated block of wood; another piece was rapidly scraped back and forth across the toothed edges. The fire plough was made in roughly the same way, with a grooved piece of wood,and another piece that was slid rapidly back and forth in the groove.

The most successful of these was the fire drill. This device consisted of a block of wood with a hole partially cut into it. A strick with a rounded end was inserted into the hole,and rotated rapidly. There were many variations in the method of rotation. The important thing was that they all produced fire.
